I am John, King of England. I ascended to the throne in 1199 and ruled until 1216. During my reign, I faced challenges that ultimately led to the loss of Normandy and other French territories to King Philip II of France. My rule was marked by the baronial revolt and the sealing of Magna Carta, both of which left a lasting impact on the constitutional development of the United Kingdom. Born on December 24, 1166, I was the youngest son of King Henry II of England and Duchess Eleanor of Aquitaine. My nickname "Lackland" speaks to the unexpected path that led me to inherit the crown.
